Amusing, but feels really similar to SCP-866. Both are computers capable of simulating an entire universe. 866's hook is that it's simulating OUR universe, and the glitches we introduced to it had terrible consequences.

The artist in medical could be (and probably is) undergoing experiments in medical. I'll see about adding a little more detail to her outcome.

The stroke affected the ventral striatum, which is thought to be involved in motivation and reward1 , the addiction process2 and is also affiliated with OCD3. The suggestion is that both the subject's OCD and compulsion to interact with the machine are correlated with the same area of the brain, which was affected by stroke, and in this case changed the way he subject's compulsions work.

Note that although his OCD is relieved, the subject has lost motivation to do anything.
